Abstract

PROBLEM TO BE SOLVED: To enable a decorative panel to be easily mounted on or dismounted from a casing body and improved in workability by a method wherein a magnet is provided on either the surface of a casing which confronts the decorative panel or the backside of the decorative panel, and a member which is attracted to a magnet is provided to the other surface. SOLUTION: A magnet sheet 6 of continuous length is laminated on the backside of a nearly rectangular decorative panel 3, and a flat metal plate 7 of continuous length is laminated on the trapezoidal top surface of a casing (cover) 2. The magnet sheet 6 and the metal plate 7 are provided at positions so as to confront each other, and a magnetic force high in intensity enough to hold the decorative panel 3 is produced between the magnet sheet 6 and the metal plate 7 in a state such that the decorative panel 3 is mounted on the cover 2. Furthermore, an opening is provided near one of the peripheral edges of the decorative panel 3, and a rotary-type handle 8 or a nearly semicircular frame-like member is mounted there. The handle 8 is fixed rotatably to the decorative panel 3 by a rotary shaft 9, and the decorative panel 3 can be dismounted from the cover 2 by pulling the frame-like member toward you.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of a decorative panel mounting structure of the present invention will be described with reference to FIG. Since the example shown in FIG. 1 is obtained by applying the structure of the present invention to the notification unit of the wireless call system shown in FIGS. 3 and 4, the same components as those shown in FIGS. And a detailed description thereof will be omitted.

As shown in FIG. 4, the notification unit has a built-in printed circuit board on which electronic components are mounted, a substantially box-shaped base 1 having an upper opening, and a base 1 so as to close the opening of the base 1. And a transparent decorative panel 3 attached to the front side of the cover 2.

On the front side of the cover 2, a setting unit cover 4 detachably attached to the cover 2 is attached.
During normal use, the setting unit cover 4 is
Is attached to the cover 2 by locking the locking projections 4a provided on the setting section cover 4 with the locking recesses 2a provided on the setting section, and the setting section (for changing the setting of the notification unit). (Not shown). Further, eight display units 5 are provided on the surface of the cover 2,
The display unit 5 corresponding to the transmitter that has transmitted the wireless signal is illuminated.

Further, the display section 5 provided on the surface of the cover 2 is provided on the upper surface of a trapezoidal portion having a substantially rectangular shape in plan view, and the bottomed box-shaped decorative panel 3 having an opening below is provided. Is attached to the cover 2 so as to cover the upper and side surfaces of the trapezoidal portion. Conventionally, the decorative panel 3 is mounted on the cover 2 by attaching screws, or the decorative panel 3 is mounted on the cover 2 by providing a pair of locking portions between the decorative panel 3 and the cover 2. In this case, the decorative panel 3 is attached to the cover 2.

FIG. 1A is a perspective view of a notification unit,
(B), (c) is principal part sectional drawing. As shown in the figure,
A long sheet-shaped magnet sheet 6 is adhered to the rear side of the short side of the substantially rectangular decorative panel 3 in a plan view, and a long flat plate is provided on the upper surface of the trapezoidal portion of the cover 2. A metal plate 7 is attached. FIG. 1 (b)
As shown in the figure, the magnet sheet 6 and the metal plate 7 are stuck at positions facing each other, and when the decorative panel 3 is attached to the cover 2, there is a decorative panel between the magnet sheet 6 and the metal plate 7. 3 is configured such that a magnetic force sufficient to hold the magnetic field 3 acts. With such a configuration, the decorative panel 3 can be easily attached to the cover 2 and workability can be improved.

Further, as shown in FIG. 1 (c), a substantially rectangular opening in a plan view is provided near one long side peripheral edge of the decorative panel 3, and the opening is closed so as to close the opening. Two rotating handles 8 are mounted. The rotary handle 8 is a frame-like member having a substantially semicircular shape in a plan view, and a rotation shaft 9 provided substantially in parallel with the surface of the decorative panel 3 so that the rotation center is near the center of the linear portion of the frame. In addition, it is rotatably attached to the decorative panel 3.

As shown in FIG. 1C, the rotary handle 8 is rotated to expose a flat portion of the frame, which is substantially flush with the surface of the decorative panel 3, to the outside of the decorative panel 3. In addition, the curved surface portion of the substantially semicircular frame in a plan view can be made to protrude from the surface of the decorative panel 3. At the time of normal use, a flat portion substantially flush with the surface of the decorative panel 3 is exposed to the outside of the decorative panel 3. Exposed rotary handle 8
Is pressed to rotate the rotary handle 8 so that the curved surface portion of the frame projects from the surface of the decorative panel 3.
Since the curved portion of the frame projecting from the surface of the decorative panel 3 serves as a handle, the decorative panel 3 can be easily removed from the cover 2 by hooking a finger on the handle and pulling it forward.

Next, a different embodiment of the decorative panel mounting structure of the present invention will be described with reference to FIG. In the example shown in FIG. 2, similarly to the embodiment shown in FIG. 1, a long sheet-shaped magnet sheet 6 is attached to the back side of the decorative panel 3 and a long sheet is provided on the upper surface of the trapezoidal portion of the cover 2. The decorative panel 3 is attached to the cover 2 by attaching a flat metal plate 7 and magnetic force acting between them. The difference from the configuration shown in FIG. 1 lies in the structure for removing the decorative panel 3.

FIG. 2A is a perspective view of the notification unit,
(B) is a perspective view of the setting unit cover 4, and (c) is a cross-sectional view. As shown in (a) and (c), a substantially rectangular locking recess 3a in plan view is provided near one long side peripheral edge of the surface of the decorative panel 3, and the locking recess 3a is provided. Of the inner side surfaces, the upper side surface is removed, and an opening 3b communicating with the back side of the decorative panel 3 is formed.
The decorative panel 3 may be removed by hooking the distal end of a tool having a hook-like shape (convex engaging portion) into the opening 3b. The example shown in FIG. 2C is characterized in that the setting portion cover 4 is configured to be used as a tool having a hook-like shape.
The cover 2 can be removed by hooking a locking projection 4a (convex locking portion) provided for attaching the cover 2 to a locking concave portion 3a provided in the cover 2.

Note that the locking recess or the locking projection is not limited to the shape shown in the embodiment. Further, in the embodiment, the magnet is described as a magnet sheet, and the member attracting the magnet is a metal plate. However, the present invention is not limited to this. It is not something to be done.

[0022]

According to the decorative panel mounting structure of the present invention, the decorative panel can be easily mounted on the housing main body, and the workability can be improved.

According to the second aspect of the present invention, there is no need to prepare a tool when removing the decorative panel.
